It can also be applied to other communication systems, as long as there is an entity in the communication system that needs to instruct to communicate with another entity, the other entity needs to interpret the advance data transmission in some way, for example, it can be applied between network equipment and terminal equipment. scheduling between multiple data blocks, or two terminal devices, one of which undertakes the function of accessing the network, etc. Specifically, the communication system can be, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (Code Division Multiple Access, CDMA) system, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (Long Term Evolution, LTE) system, Advanced Long Term Evolution LTE-A (LTE Advanced) system, LTE Frequency Division Duplex (Freq Terminal Equipment) ncy Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.

Those skilled in the art can use the technical solutions provided in the embodiments of this application to perform wireless communication between network equipment and terminal equipment, such as wireless communication between access network equipment and terminal equipment, and wireless communication between core network equipment and terminal equipment .

The NR system mainly supports Enhanced Mobile Broadband (eMBB) services to meet the requirements of high speed, high spectral efficiency, and large bandwidth. In practical applications, in addition to eMBB services, there are many other types of services, such as industrial IoT sensors, surveillance cameras, and data transmission services for wearable devices. Terminals supporting these services have the advantages of large number of connections, low power consumption, and low cost. Compared with terminals that support eMBB services, the hardware capabilities are reduced, such as reduced supported bandwidth, reduced processing speed, reduced number of antennas, etc. This type of terminal is called a reduced capability (Reduced Capability, RedCap) type of terminal . Therefore, the NR system needs to be optimized for low-capacity terminals supporting the above-mentioned other service types, and the corresponding system is called the NR-light system.

In the NR-light system, compared with the non-RedCap terminal, the reception performance of the downlink channel of the RedCap terminal is reduced due to the reduction in the number of receiving antennas. In the random access process, the network device sends Msg2, Msg4 or MsgB to the terminal through the common channel. Usually, the transmission mode of the downlink channel is set according to the default number of receiving antennas of the RedCap terminal (for example, 1 receiving antenna), such as the size of the scheduling resource. , modulation and coding schemes, etc., which will reduce the downlink spectral efficiency.

In order to solve the above problem, an embodiment of the present application provides an information transmission method. In the method, during the random access process, the terminal device reports the device type or receiving capability of the terminal device to the network device through various reporting methods, wherein the terminal device Devices include RedCap type and non-RedCap type end devices. After learning the device type or receiving capability of the terminal, the network device transmits data or signaling by using the corresponding downlink channel transmission mode, thereby improving the utilization rate of the downlink spectrum.

In an embodiment of the present application, the terminal device carries indication information through a physical random access channel (Physical Random Access Channel, PRACH), and the indication information is used to indicate the device type or receiving capability of the terminal device. Exemplarily, the terminal device may indicate different device types (such as RedCap type and non-RedCap type) or receiving capabilities (such as the number of receiving antennas) through different preambles, initial uplink bandwidth parts (BWP) or PRACH resources. is 1, and the number of receiving antennas is 2).

In an embodiment of the present application, the terminal device carries indication information through a Physical Uplink Shared Channel (PUSCH), and the indication information is used to indicate the device type or receiving capability of the terminal device. Exemplarily, the terminal device can use different PUSCH scrambling codes, PUSCH demodulation reference signal (Demodulation Reference Signal, DMRS) sequences, or different PUSCH configurations (including PUSCH resource configuration, configure some configuration parameters of PUSCH), DMRS configuration of PUSCH (including PUSCH DMRS resource configuration, configuring some configuration parameters of PUSCH DMRS), indicating different device types (such as RedCap type and non-RedCap type) or receiving capabilities (such as the number of receiving antennas is 1, the number of receiving antennas is 2 ).

Before introducing the technical solutions provided in this application, the random access process of the current NR system is first introduced.

At present, the random access procedure in the NR system includes the following two types: a 4-step random access procedure (4-Step RACH procedure) and a 2-step random access procedure (2-Step RACH procedure). The delay overhead of the 4-Step RACH process is relatively large, and it is not suitable for the low-latency and high-reliability scenarios in 5G. In this regard, the 2-Step RACH process was introduced in NR R16, which can reduce the access delay compared with the 4-Step RACH process.

FIG. 2 is a schematic diagram of a random access process provided by an embodiment of the present application. As shown in FIG. 2 , the random access process provided by this embodiment is a 4-Step RACH process, which mainly includes the following steps:

Step 201, the UE sends Msg1 to the gNB through the physical random access channel PRACH.

Msg1 includes the random access preamble sequence preamble. The gNB detects the preamble, and the gNB executes step 202 in response to the random access request of the UE.

Step 202, the gNB sends a Msg2 including a random access response (random access response, RAR) to the UE.

The RAR in Msg2 is used to inform the UE of the PUSCH resources that can be used when sending Msg3, allocate a Radio Network Temporary Identifier (RNTI) to the UE, and provide the UE with a timing advance time advance command, etc.

Step 203, the UE sends the Msg3 to the gNB according to the indication of the RAR.

The UE sends Msg3 on the PUSCH resource specified by the random access response message, and Msg3 carries the UE-specific temporary identity information.

Step 204, the gNB sends Msg4 to the UE.

Msg4 includes a contention resolution message and allocates uplink transmission resources for the UE at the same time. When the UE receives the Msg4 sent by the gNB, it will check whether the UE-specific temporary identity sent by the UE in Msg3 is included in the contention resolution message sent by the gNB. If it fails, the UE needs to initiate the random access procedure from step 201 again.

FIG. 3 is a schematic diagram of a random access process provided by an embodiment of the present application. As shown in FIG. 3 , the random access process provided by this embodiment is a 2-Step RACH process, which mainly includes the following steps:

Step 301, the UE sends the MsgA to the gNB.

MsgA includes Msg1 and Msg3 in the 4-Step RACH process. For example, MsgA includes the preamble, the identity of the UE, and the PUSCH part. Among them, the random access opportunity (RACH occasion, RO) where the preamble is located is the same as the 4-Step RACH process, which can be configured through the network, and its RO can be shared with the RO of the 4-Step RACH, or can be configured separately. The time-frequency resource where the PUSCH is located is called the PUSCH occurrence (PO). One PO can contain multiple PUSCH resource units (PUSCH resource units, PRUs), one PRU contains PUSCH resource and DMRS, DMRS contains DMRS port (DMRS Port) and DMRS sequence (Orthogonal Frequency Division Multiple Access) (DMRS sequence (for OFDMA) )). PO is also configured through the network, and its period is the same as that of RO, and the two have an associated relationship.

Step 302, the gNB sends the MsgB to the terminal device.

MsgB includes Msg2 and Msg4 in the 4-Step RACH process. For example, MsgB includes a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) and a physical downlink control channel (Physical Downlink Control Channel, PDCCH) parts.

Similar to step 204, the MsgB includes a contention resolution message and allocates uplink transmission resources for the UE. When the UE receives the MsgB sent by the gNB, it will check whether the UE-specific temporary identity sent by the UE in the MsgA is included in the contention resolution message sent by the gNB. If it fails, the UE needs to initiate the random access procedure from step 301 again.

It should be noted that the technical solutions provided by the embodiments of the present application may be implemented in the random access process shown in FIG. 2 , or may be implemented in the random access process shown in FIG. 3 .

The technical solutions provided by the embodiments of the present application will be described in detail below through specific embodiments. It should be noted that the technical solutions provided by the embodiments of the present application may include part or all of the following contents, the following specific embodiments may be combined with each other, and the same or similar concepts or processes may be in some embodiments No longer.

FIG. 4 is an interactive schematic diagram of an information transmission method provided by an embodiment of the present application. As shown in FIG. 4 , the method provided by this embodiment includes the following steps:

Step 401: The terminal device generates indication information, where the indication information is used to indicate device information of the terminal device.

The device information of the terminal device includes at least one item of the device type of the terminal device and the number of receiving antennas. Device types (or terminal types) include RedCap terminals or non-RedCap terminals. Optionally, the device type may further include further subdivisions of RedCap terminals, for example, including RedCap terminal type 1, RedCap terminal type 2, and the like. The number of receiving antennas includes one receiving antenna, two receiving antennas, or more than two receiving antennas.

Step 402: The terminal device sends indication information to the network device, and the indication information is carried by the PUSCH.

The PUSCH is the PUSCH in Msg3, or the PUSCH in MsgA. specific,

In an embodiment of the present application, in the 4-Step RACH process, the terminal device may carry indication information through the PUSCH in Msg3, and the indication information is used to indicate the device type or receiving capability of the terminal device.

In an optional solution, the terminal device may carry the indication information through the scrambling code of the PUSCH in Msg3. Terminals with different device types or different receiving capabilities correspond to different Msg3 PUSCH scrambling codes. Exemplarily, for a RedCap terminal, when the terminal sends a Msg3 PUSCH to a network device, it can implicitly indicate to the network the device type or receiving capability of its terminal by using a different Msg3 PUSCH scrambling code from that of the non-RedCap terminal.

As an example, the scramble code of the PUSCH of the Msg3 carrying the indication information has a corresponding relationship with the device information of the terminal device, that is, terminals of different device types or receiving capabilities correspond to different scramble codes of the PUSCH of the Msg3. The scrambling code of the PUSCH of Msg3 is determined according to the first initialization value, and different first initialization values generate different scrambling codes of the PUSCH of Msg3. Therefore, as another example, the first initialization value and the device information of the terminal device have Correspondence.

In one case, the first initialization value of the scrambling code for generating the PUSCH of Msg3 can be determined according to the first parameter, which includes at least one of the terminal's wireless network temporary identifier and the data scrambling code identifier.

c _int =n _RNTI ·2 ¹⁵ +n _ID Formula 1

In the formula, c _int represents the first initialization value of the PUSCH scrambling code for generating Msg3; n _RNTI represents the wireless network temporary identifier of the terminal; n _ID represents the data scrambling code identifier, that is, the value of the high-level parameter dataScramblingIdentityPUSCH, n _ID ∈ (0, 1,…,1023). For the transmission of Msg3 in the random access process, if a TC-RNTI (temporary C-RNTI) is allocated by the upper layer, n _RNTI is TC-RNTI, otherwise n _RNTI is C-RNTI (Cell-RNTI).

It can be seen from formula 1 that when the n _ID is unchanged, different n _RNTIs correspond to different c _ints , and different c _ints generate different Msg3 PUSCH scrambling codes, and different scrambling codes correspond to different device types or receiving capabilities. terminal. Therefore, as an example, the n _RNTI has a corresponding relationship with the device information of the terminal device.

Alternatively, when the n _RNTI is unchanged, different n _IDs correspond to different _cints , and different _cints generate different PUSCH scrambling codes of Msg3, and different scrambling codes correspond to terminals of different device types or receiving capabilities. Therefore, as an example, the n _ID has a corresponding relationship with the device information of the terminal device.

Alternatively, the device type or receiving capability of the terminal is jointly indicated by n _RNTI and n _ID .

In the above case, the terminal device may carry the indication information through the original parameter (eg, n _RNTI or n _ID ) in the calculation formula of the first initialization value, indicating the device type or receiving capability of the terminal.

In another case, the first initialization value of the scrambling code for generating the PUSCH of Msg3 may be determined according to the second parameter, and the second parameter is a newly added parameter. Exemplarily, the second parameter is set to n _RC , and formula one can be modified to formula two.

c _int =n _RNTI · 2 ^y +n _ID · 2 ^x +n _RC formula 2

In the formula, x depends on the value range of n _RC , if the value range of n _Rc is {0, N-1}, then x=log ₂ (N), y=x+a, a corresponds to the value of n _ID Value range, n _ID ∈(0,1,…,1023), eg a=15. The value of N depends on the number of indicated device types. For example, if a RedCap terminal type and a non-RedCap terminal type are indicated, N takes 2. For example, if

RedCap terminal types

1, 2, 3, and 4 are indicated, N takes 4.

Different n _RCs can be used to carry different indications, such as:

n _RC = 0 indicates that the RedCAP terminal type is 1, or the number of receiving antennas is 1;

n _RC =1 indicates that the RedCAP terminal type is 2, or the number of receiving antennas is 2.

In the above case, the terminal device adds a new parameter to the calculation formula of the first initialization value, and carries the indication information through the new parameter value, indicating the device type or receiving capability of the terminal.

It can be seen from the above description that the above optional solution can carry indication information through different scramble codes of the PUSCH of Msg3, without adding new indication information, which is simple to implement and has good backward compatibility.

In an optional solution, the terminal device may carry the indication information through the DMRS sequence of the PUSCH in Msg3. Terminals with different device types or different receiving capabilities correspond to different DMRS sequences of Msg3 PUSCH. Exemplarily, for a RedCap terminal, when the terminal sends the DRMS of the Msg3 PUSCH to the network device, it can implicitly indicate to the network the device type or receiver of the terminal by using a DMRS sequence of the Msg3 PUSCH different from that of the non-RedCap terminal. ability.

As an example, the sequence of the PUSCH DMRS of the Msg3 carrying the indication information has a corresponding relationship with the device information of the terminal device, that is, terminals of different device types or receiving capabilities correspond to different sequences of the PUSCH DMRS of the Msg3. The sequence of the PUSCH DMRS of Msg3 is determined according to the second initialization value, and different second initialization values generate different sequences of the PUSCH DMRS of Msg3. Therefore, as another example, the second initialization value and the device information of the terminal device have Correspondence.

In one case, the second initialization value of the sequence of the PUSCH DMRS for generating Msg3 can be determined according to the third parameter, and the third parameter includes the symbol position of the DMRS, the number of symbols, the code grouping (CDM group), and at least one of the scrambling parameters. , please refer to Equation 3 for details.

In the formula,

Determined by high-level configuration parameters, when not configured,

Indicates the cell ID. When the upper layer configures the parameter dmrs-Uplink-r16,

hour,

λ is the CDM group of DMRS, λ∈(0,1). n _SCID ∈(0,1), indicated by DCI format 0_1 or 0_2, or indicated by high-level parameters, or determined according to the association between preamble and PUSCH timing and DMRS resources in the 2-Step RACH process, otherwise n _SCID = 0.

It can be seen from formula 3 that when other parameters remain unchanged, different scrambling parameters correspond to different _cints , different _cints generate different PUSCH DMRS sequences of Msg3, and different DMRS sequences correspond to different device types or receiving capabilities. terminal. Therefore, as an example, the scrambling parameter has a corresponding relationship with the device information of the terminal device.

Alternatively, when other parameters remain unchanged, the symbol positions of different DMRSs correspond to different _cints , different _cints generate different PUSCH DMRS sequences of Msg3, and different DMRS sequences correspond to terminals of different device types or receiving capabilities. Therefore, as an example, the symbol position of the DMRS has a corresponding relationship with the device information of the terminal device.

Or, under the condition that other parameters remain unchanged, the number of symbols of different DMRS corresponds to different c _int , different c _int generates different PUSCH DMRS sequences of Msg3, and different DMRS sequences correspond to terminals of different device types or receiving capabilities . Therefore, as an example, the number of symbols of the DMRS has a corresponding relationship with the device information of the terminal device.

Alternatively, when other parameters remain unchanged, different DMRS CDM groups correspond to different _cints , different _cints generate different PUSCH DMRS sequences of Msg3, and different DMRS sequences correspond to terminals of different device types or receiving capabilities. Therefore, as an example, the CDM group of the DMRS has a corresponding relationship with the device information of the terminal device.

Alternatively, the device type or receiving capability of the terminal is jointly indicated by at least two items of the symbol position of the DMRS, the number of symbols, the CDM group, and the scrambling parameter.

In the above case, the terminal equipment can carry the indication information through the original parameters in the calculation formula of the second initialization value (such as DMRS symbol position, number of symbols, CDM group or scrambling parameters) to indicate the equipment type or receiving capability of the terminal.

In another case, the second initialization value of the sequence for generating the PUSCH DMRS of Msg3 may be determined according to the fourth parameter, and the fourth parameter is a newly added parameter. Exemplarily, the fourth parameter is set to n _RC , and formula three can be modified to formula four.

Different n _RCs can be used to carry different indications, such as:

In the above case, the terminal device adds a new parameter to the calculation formula of the second initialization value, and carries the indication information through the new parameter value, indicating the device type or receiving capability of the terminal.

As can be seen from the above description, the above-mentioned optional solution can not add new indication information through different bearer indication information of the PUSCH DMRS sequence of Msg3, which is simple to implement and has good backward compatibility.

In an embodiment of the present application, in the 2-Step RACH process, the terminal device can carry indication information through the PUSCH in the MsgA, and the indication information is used to indicate the device type or receiving capability of the terminal device.

In an optional solution, the terminal device may carry the indication information through the scrambling code of the PUSCH in the MsgA. Terminals with different device types or different receiving capabilities correspond to different MsgA PUSCH scrambling codes. Exemplarily, for a RedCap terminal, when the terminal sends a MsgA PUSCH to a network device, it can implicitly indicate to the network the device type or receiving capability of its terminal by using a different MsgA PUSCH scrambling code from that of a non-RedCap terminal.

As an example, the scramble code of the PUSCH of the MsgA carrying the indication information has a corresponding relationship with the device information of the terminal device, that is, terminals of different device types or receiving capabilities correspond to different scramble codes of the PUSCH of the MsgA. The scramble code of the PUSCH of MsgA is determined according to the first initialization value, and different first initialization values correspond to different scramble codes of the PUSCH of MsgA. Therefore, as another example, the first initialization value and the device information of the terminal device have Correspondence.

In one case, the first initialization value of the scrambling code of the PUSCH for generating the MsgA can be determined according to the first parameter including the wireless network temporary identifier of the terminal, the data scrambling code identifier and the random access preamble index. For details, please refer to Formula 5.

c _int =n _RNTI ·2 ¹⁶ +n _RAPID ·2 ¹⁰ +n _ID Formula 5

In the formula, c _int represents the first initialization value of the PUSCH scrambling code for generating MsgA; n _RNTI represents the wireless network temporary identifier of the terminal; n _ID represents the data scrambling code identifier, that is, the value of the high-level parameter msgA-dataScramblingIdentity, n _ID ∈ ( 0,1,…,1023), otherwise

Indicates the cell ID.

It can be seen from formula 5 that when n _RAPID and n _ID remain unchanged, different n _RNTIs correspond to different cints, different _cints correspond to different PUSCH scrambling codes of _MsgA , and different scrambling codes correspond to different device types or receiving capability of the terminal. Therefore, as an example, the n _RNTI has a corresponding relationship with the device information of the terminal device.

Or, under the condition that n _RAPID and n _RNTI remain unchanged, different n _IDs correspond to different cints, different _cints generate different PUSCH scrambling codes of _MsgA , and different scrambling codes correspond to different device types or receiving capabilities. terminal. Therefore, as an example, the n _ID has a corresponding relationship with the device information of the terminal device.

Or, under the condition that n _ID and n _RNTI remain unchanged, different n _RAPIDs correspond to different cints, different _cints generate different PUSCH scrambling codes of _MsgA , and different scrambling codes correspond to different device types or receiving capabilities. terminal. Therefore, as an example, n _RAPID has a corresponding relationship with the device information of the terminal device.

Alternatively, at least two items of n _RNTI , n _ID or n _RAPID are used to jointly indicate the device type or reception capability of the terminal.

In the above case, the terminal device may carry the indication information through the original parameters (eg, n _RNTI , n _ID or n _RAPID ) in the calculation formula of the first initialization value, indicating the device type or receiving capability of the terminal.

In another case, the first initialization value of the scrambling code for generating the PUSCH of the MsgA may also be determined according to the second parameter, and the second parameter n _RC is a newly added parameter. Exemplarily, formula five can be modified to formula six.

C _int =n _RNTI ·2 ^16+x +n _RAPID ·2 ^10+x +n _ID ·2 ^x +n _RC formula 6

In the above case, the terminal device adds a new parameter to the calculation formula of the first initialization value, and carries the indication information through the new parameter, indicating the device type or receiving capability of the terminal.

It can be seen from the above description that the above optional solution can carry indication information through different scramble codes of the PUSCH of MsgA, without adding new indication information, the implementation is simple, and the backward compatibility is good.

In an optional solution, the terminal device may carry the indication information through the DMRS sequence of the PUSCH in the MsgA. Terminals with different device types or different receiving capabilities correspond to different DMRS sequences of the MsgA PUSCH. Exemplarily, for a RedCap terminal, when the terminal sends the DRMS of the MsgA PUSCH to the network device, it can implicitly indicate to the network the device type or receiver of the terminal by using a DMRS sequence of the MsgA PUSCH different from that of the non-RedCap terminal. ability.

As an example, the sequence of the PUSCH DMRS of the MsgA carrying the indication information has a corresponding relationship with the device information of the terminal device, that is, terminals of different device types or receiving capabilities correspond to different sequences of the PUSCH DMRS of the MsgA. Similar to the sequence of the DMRS of the Msg3 PUSCH, the sequence of the DMRS of the MsgA PUSCH is determined according to the second initialization value, and the calculation formula of the second initialization value can refer to the formula three or formula four of the above-mentioned embodiment, and will not be repeated here. The terminal device may carry the indication information through the original parameter or the newly added parameter in the calculation formula of the second initialization value, indicating the device type or receiving capability of the terminal.

It can be seen from the above description that the above-mentioned optional solution can not add new indication information through different bearer indication information of the PUSCH DMRS sequence of the MsgA, which is simple to implement and has good backward compatibility.

In an embodiment of the present application, in the 4-Step RACH process or the 2-Step RACH process, the information carried by the PUSCH includes indication information, and the indication information is used to indicate the device type or receiving capability of the terminal device. The difference between the indication information in this embodiment and the above-mentioned embodiments is that the indication information displayed indicates the device type or receiving capability of the network terminal.

In the prior art, the PUSCH in Msg3 or MsgA may carry the identity of the UE for conflict resolution and high-level information of the reason for establishing the connection. In the above embodiment, the indication information may also be carried in the PUSCH in Msg3 or MsgA.
